Fully 3d printed gun with functioning mag

i made this to see if i can make a fully 3d printed gun, this is a small part of it and more of this will be coming soon, from what ive tested so far it can hold 3 bullets but im gonna continue working on this for later, you should weld the bottom part to the magazine using the 3d printer hotend.THIS IS NOT A REAL GUN AND DOES NOT SHOOT
